RNDTEST(4) Kernel Interfaces Manual RNDTEST(4) NAME rndtest -- FIPS 140-2 random number generator test monitor SYNOPSIS device rndtest DESCRIPTION The rndtest driver "hooks up" to hardware crypto devices to monitor the entropy data passed to the random(4) subsystem. This data is periodi- cally tested for FIPS 140-2 compliance and statistics are collected. If the harvested entropy fails any of the FIPS test suite, then it is discarded and testing is continuously applied until "good data" is re- ceived from the device. Failures are optionally reported on the con- sole. SEE ALSO crypto(4), hifn(4), random(4), safe(4), crypto(9) HISTORY The idea for this and the original code came from Jason L. Wright. The rndtest device driver first appeared in FreeBSD 5.0. BUGS Crypto device drivers must be compiled specially to make use of this driver; this should not be necessary. This feature might better be in- tegrated into the random(4) subsystem where it can be applied to de- vices that claim to supply "pure entropy". FreeBSD 15.0 May 11, 2020 RNDTEST(4)
